What has been your most satisfying component?


I don't think I have seen this question asked so here it goes. Many of us tend to buy and sell looking for the ideal, the holy grail, what works best in the current system, or whatever.
What component (or components)have stood the test of time in your system? I've been through quite a few but some have stayed despite having bought their replacements and subsequently selling them. I'll share once we get a few posts to get things going.

Can't say that they stood the test of time yet, but so far so good - ARC CD3MkII cd player and Pass Labs X250.5 amplifier.

The component that stood the test of time in my system was an ARC LS-15 preamp - almost 7 years!
I would say it's a toss up for me. I bought a Aragon 8008bb from a fellow goner and it made a big improvement in my system. Also up there is my Ps Audio P-300 Power Plant. Also has made a big diff. I'm missing it right now, it's out being modified. Can't wait to get it back.
My Linn LP12 Lingo. My once and future TT, through many upgrades. It has a Graham on it now with a Koetsu that's just breaking in. Gorgeous. And a hat tip to my Klyne SK-5A preamp.
okay, maybe the brain and ears are not audio components.

my favorite audio component was and still is the quad esl.
